Oversized, outrageous Mary Alice and her prim sister Patricia Anne have been looking forward to the gala benefit being staged to raise money for the restoration of Vulcan, Birmingham's ever-tarnishing unnatural wonder. And what a show it is, with a grand finale that has thirty sequined Elvis impersonators high-kicking in unison! From the front row, Mouse and Sister have a perfect view of the action when one of the dancing Kings keels over dead into the bandstand. This Elvis clone has not only left the building ... he's left this life, courtesy of a switchblade knife in the back. And when the murder weapon turns up in Patricia Anne's very sensible purse, the perennially law-abiding Mouse is understandably all shook up. Suspicious minds have her pegged as the prime suspect in this bizarre case of Elvis elimination. And if she doesn't do some serious sleuthing, she could end up doing the Jailhouse Rock!
